Abstract
Background
The risk factors along with demographic and angiographic features associated with aorto-ostial atherosclerotic coronary artery disease usually differ from that of non-aorto-ostial atherosclerotic coronary artery disease.
Objectives
This study was designed to evaluate etiology of aorto-ostial atherosclerotic coronary artery disease involving left main coronary artery (LMCA), right coronary artery or both with consideration of clinical risk factors, demographic and angiographic features.
Methods
A total of 7356 angiograms over 2 years in continuation were analyzed.
Results
116 patients were found to have aorto-ostial coronary artery disease with prevalence of 1.5. A total of 95 patients who have complete data were analyzed. Mean age was 59 ± 10 years. Prevalence in males was 5.7 times greater than female. Isolated ostial LMCA was 2 times more prevalent than isolated ostial RCA. Hypertension, diabetes and smoking were the main risk factors. 34.7% of the patients had hypercholesterolemia (> 180 mg/dl) and 26.3% of the patients had hypertriglyceridemia (> 150 mg/dl). High TC/HDL (> 3.5) ratio was seen in 77.9% of the patients. When ostial LMCA group was compared with ostial RCA group hypertriglyceridemia (Odds ratio 9.8, 95% CI, 1.7–4.2, P < 0.001) and hypercholesterolemia (Odds ratio 7.05, 95% CI, 1.7–5.7, P < 0.001) emerged as independent risk factors for ostial LMCA disease.
Conclusion
Overall there is 1.5% prevalence of atherosclerotic aorto-ostial disease of coronary arteries among patients of atherosclerotic coronary artery disease and higher proportions of patients are of male sex. Hypercholesterolemia, hypertriglyceridemia and high TC/HDL ratio can be considered as risk factors for aorto-ostial atherosclerotic coronary artery disease.
